Amazon EC2 Goes Dark In Morning Cloud Outage

Amazon Web Services Thursday morning scrambled to fix issues with its Elastic Compute Cloud (EC2) and Relational Database Service cloud computing services, which suffered outages and interruptions overnight that took down a host of popular Web sites.

According to AWS's status dashboard and service updates, the company began investigating connectivity and latency issues around EC2 instances in its U.S. East Coast region at 4:41 a.m. Eastern. It appears the issues only affected Amazon's North Virginia data center.

The issues persisted. In a 5:49 a.m. update, Amazon said it continued to see connectivity errors impacting EC2 instances. Additionally, Amazon was "also experiencing delayed launches for EBS backed EC2 instances in affected availability zones in the US-East-1 region."

As of 6:20 a.m., service began to recovery, and by 8:02 a.m. Eastern AWS said "latency has recovered for a portion of the impacted EBS volumes. We are continuing to work to resolve the remaining issues with EBS volume latency and error rates in a single Availability Zone."

Come 9:09 a.m. Eastern, API errors and volume latencies in the affected ability zones remained, Amazon said. And at just before 10 a.m., Amazon wrote "there has been a moderate increase in error rates for CreateVolume. This may impact the launch of new EBS-backed EC3 instances in multiple availability zones in the US-East-1 region. Launches of instances store AMIs are currently unaffected."

Amazon did not respond to a request for comment as of press time.

The outage affected a host of big name Amazon EC2 cloud customers, including popular Web sites like Foursquare, HootSuite, Quora and Reddit.

Early Thursday morning, Reddit visitors were met with the message: "Amazon is currently experiencing a degradation. They are working on it. We are still waiting for them to get to our volumes. Sorry."

Meanwhile, Quora, a newcomer social site that lets people ask and answer questions said "We'll be back shortly, we hope. Sorry, it sucks for us too. We'd point fingers, but we wouldn't be where we are today without EC2." Quora's Web site was offline as of 10 a.m.

Popular Twitter application and Web site HootSuite also suffered issues and tweeted: "Our web hosting provider (EC2) is still working hard resolving the service disruption. We will keep you posted."

Doron Kempel says selling hyper-convergence can be challenging for solution providers, but success will come from taking business from competitors that are unprepared or hesitant to embrace the technology.
